Robert Duvall does not play Robot Devil, but wouldn’t it be cool if he did?

Loved the rope-sawing competition on last week’s “Rivals II,” especially the public peeing preface Cooke contributed. And then there was the psycho romance meltdown undertaken by Anastasia and CT. It’s no challenge to keep up with the MTV “Challenge.”

Spoilers for tonight’s “Big Brother” lurk in invisotext:

* Viewers inexplicably turned on Elissa and put her on the nomination block alongside Aaryn and Kaitlin

* Elissa won the Power of Veto and pulled herself off the block.

* Viewers picked GinaMarie to take take Elissa’s place on the nomination block, so now all three members of the Hot Widows’ alliance – Aaryn, Kaitlin and GinaMarie – are competing to avoid eviction.

* Judd and Helen are pushing for Kaitlin to go because she’s the greatest threat among the Widows, and the thinking is Aaryn will be easy to ditch later.

* Meanwhile, Howard, Spencer, Andy and Judd apparently hatched a new alliance, but I’m uncertain how seriously Andy and Judd are taking it.

* Aaryn only learned on Monday the last name of surfer boy David Girton, the evicted houseguest with whom she slept.

* On Tuesday, 28-year-old realtor Amanda wanted to know “when did CBS start?” She seems to be under the impression it’s a newer channel. Which is slightly weirder because she starred for months on a 2008 CBS Web show titled “Big Shot Live.”
